The aim of this study was to determine antioxidant activity (DPPH and phosphomolyb denum method), polyphenols content (total polyphenols, flavonoids, and phenolic acids), mineral
compounds composition (Cu, Zn, Mn, Fe, Cr, Ni, Co, Pb and Cd) and antimicrobial activity (with
disc diffusion method) of medicinal herbs traditionally used in the Slovak republic. The tested
plants belonged to the Primulaceae, Urticaceae, Grossulariaceae, Rosaceae, Lamiaceae, Asteraceae,
Equisetaceae, Tropaeolaceae, and Plantaginaceae families. The highest antioxidant activities were
found in samples of Rosa canina L. (DPPH—29.43 ± 0.11 mg TE/g; TE—Trolox equivalent) and
Fragaria vesca L. (phosphomolybdenum method—679.56 ± 3.06 mg TE/g), both from the Rosaceae
family. Total polyphenols (determined using the Folin–Ciocâlteu-reagent) were most abundant in a
sample of Fragaria vesca L.—124.51 ± 5.05 mg GAE/g (GAE—gallic acid equivalent), total flavonoids
(determined using the aluminum chloride method)—in a sample of Primula veris L.—48.35 ± 3.77 mg
QE/g (QE—quercetin equivalent), and total phenolic acids (determined using Arnova reagent)—in a
sample of Thymus serpyllum L.—102.31 ± 2.89 mg CAE/g (CAE—caffeic acid equivalent). Regarding
mineral compounds composition, samples of Fragaria vesca L. and Thymus serpyllum L. showed the
highest levels of iron. In samples of Calendula officinalis L. and Trapaeolum majus L., the highest
amounts of zinc were determined, while copper was the most abundant in samples of Urtica dioica
L. and Melissa officinalis L. The amounts of heavy metals were within legally acceptable limits. The
extract of Equisetum arvense L. showed the strongest inhibitory activity towards Clostridium perfrin gens CCM 4991 (6 mm), while the one from Mentha piperita L.—towards Candida glabrata CCM 8270
(4.83 mm) and Candida tropicalis CCM 8223 (4.33 mm).
